Elachistus ohioensis (MS.)Ashmead.—Reared from pupæ, in which stage it probably passes the winter; found November 7th, within the shells of beech-nuts, the kernels of which had been attacked and eaten by some kind of larva which had burrowed out these kernels, leaving only a mass of excrement. A hole in the shells indicated an attack similiar to that of some species of Balaninus, though, as I found no larvæ of them, it was impossible to learn their exact nature. Locality, Wooster, Ohio.

Cirrospilus flavicinctus, Riley.—This was described in Lintner's First Report as being reared from Bucculatrix pomifoliella, Clemens, in Missouri, and also New York. My rearings were from Aspidisca splendoriferella, Clem., the cocoons of which were collected near Cleveland, Ohio.
